From what I heard about the race in Portland, the foam tires had no bite on the nitro cars either and they, too, wore out prematurely. That is very unusual.
Obviously the track has a huge impact on what works and what doesn't. These tires were developed by testing at the Florida state series- all asphalt tracks. The fact that they work on carpet is an added bonus. Until someone tries greens at that track, I think it is premature to pass judgement on the tires' performance.

Being more of a carpet racer, I an anxious to try them on the rug.

When people say these tires are slower in their opinion they are referring to tenths of second per lap which MAY add up to 3-4 seconds during an entire race. I can guarantee that we are all responsible for more time loss than that on the track by clipping dots and boards.
So, with that in mind, can we get back on point, and get a workable solution for the Jaco Tires.
What I'm hearing is that you need more camber, anyone got a starting point suggestion. I tried 2.5deg, have others tried more? Less?
I've also heard running thicker shock oil is better. I'm currently running 35 weight oil, Corally shocks, stock pistons. I'm currently running 1.3 sway bars front and rear. Have others found going with stiffer sways to help.
Let's get a general group of setup suggestions on this board all consolidated so we can help each other.

change the inserts and these tires would be dailed. i personally think they are to flat which requires you to make your car roll more than you have with previous cs or sorex etc, tires. but wear on these tires are like slim to none, good rubber, but i think w.e inserts the jaco blues have is a no gooder.. i hope Jack will be bringing out a new bash out with a improvement (of the inserts)

If you think about it though the statement is kind of false. I drive inconsistently every run. If we are talking a .3 second per lap difference between tires on average then it is a real 7 seconds (on our track). Hard to explain but we are talking averages here. We aren't saying .3 seconds per lap slower on one particular run, on average .3 seconds slower.
I will give you setup, I won't give you that driving makes up for it. Im consistently inconsistent

I don't think anyone out there wants to be put at an immediate half lap disadvantage before the starting horn. That's why myself and others are working towards a solution for alternate tires. I don't want to put my racers at a loss right off the bat. At our track, on any given Saturday, .3 of a lap is the difference in being TQ, or being 6th.

I don't quite understand why it has been so hard for people to adapt to a new tire. Let us not forget that S-13's were the tire of choice in the beginning. Subsequent to that tire 100's of tires have come out some faster with no tire life some not faster but with an extended wear life. In the end the tire that was RELATIVELY fast and had long wear characteristics won out. We now have a similar situation. Hopefully there will be a resolution soon. All I can say is that Jaco is CONSTANTLY trying to improve the available product for its consumers.
Now back to the setup questions, as I posted before the camber link length seems to have a role in the wear of this tire. Shorter and more parallel links have worked best for me. However you may need to find that sweet spot on your car. Spring rates and oil Wt. have not had a profound effect on my particular car. I run 17 Lb front spring with a 14 Lb rear spring with 30 wt Xray oil and typically 2-3 holes open depending on the track. I always use sway bars and this may aid in limiting the sidewall roll.

I agree with what you are saying, however very few clubs or "big events" use an open tire. Perhaps I should have been more clear or concise in my statement. IF this tire is being used as a handout, no one has an advantage but if you run a Jaco blue that lasts 5-8 runs competitively against say a Yokomo 138 G that lasts exactly 1.5 runs then you will have a problem. I think it is only fair to compare apples to apples.

As to the shorter parallel links, that's a great example of what I'm trying to get everyone to place their input here so all of us can try things, and then give feedback to the manufacturer. It's interesting that you've found that spring weights and oils haven't had a big effect on the wear. Have you messed with different thickness sway bars?

Looks like greens are the way to go at my local track. Seem to last pretty well also. You really need to keep an eye on the camber though.

Guys
Are the Serpent Xceed tyres, jaco rubberz on the old dish wheel?
We dont get the Jaco Rubberz here in the uk.
